Various embodiments are described that relate to a radiating element and an engineered magnetic material. In a communication environment a radiating element can be used to communicate information, such as to send signals. Various factors, including electromagnetic factors, can influence the performance of the radiating element. In one example, if the radiating element becomes too close to a ground plane, then performance of the radiating element can suffer. To counter negative effects of being too close to the ground plane an engineered magnetic material can be employed that causes the radiating element to perform better when relatively close to the ground plane.

The invention is a low profile antenna array, particularly beneficial for AM broadcasting stations, which dramatically reduces the height of the antenna. The antenna array is constructed of at least two conductors oriented horizontally or sloping slightly up and extending away from a center location where they have upright sections extending above the ground plane by as little as 0.01 wavelength. The individual conductors are each approximately one-quarter wavelength long. The multiple conductors of the antenna array are each fed by impedance matching sections to achieve high individual impedances, which, when connected in parallel can be made to match any desired impedance with dimensional changes.
